ContentUploader provided with ContentExplorer does not call requestInterceptor option

This screen shot shows the get request form the explorer view transforming the url to the needed proxy. When utilizing the requestInterceptor option.

But when utilizing the uploader. The requestInterceptor does not seem to get called. The url remains the "api.box.com", and the proxy server never receives the request.

Angular Application utilizing the cdn url import for the content-explorer
